Cheapo Adaptall 2 mount ok for mirror lens?

GibbyTheMole · 04-06-2011, 05:26 AM

Hi.

I was thinking of picking up a Tamron SP 500mm Adaptall 2 mirror lens & was wondering, since it's a fixed aperture of f8, with no electric signals being passed to the camera anyway, would a cheap generic Adaptall 2 adapter be ok to use on this lens?

At least, I assume no electric signals are passed on a fixed aperture lens. Maybe I'm wrong.

Cheers,
Bobbo :-)

Your assumption is right on, The cheaper PK adapter will do just fine for fixed aperture, manual focus lenses.

That's what I use on mine. It works fine.
